Programming Exercises 1. Modify the Deck class to keep track of the current size of the deck using an instance variable. Does this change the run-time efficiency of the size operation? Do a bit of research to answer this question. the shuffling code in the Deck class. class to include the operations addTop, addBottom, and addRandom (the last 2. Look into the functions provided by the Python random module to simplify 3. Suppose we want to be able to place cards back into a deck. Modify the Deck one inserts the card at a random location in the deck)Step by Step Solution
